ApplicationcJune 2; 1949',- serial Noil9fig'l59l My invention is a .novel ineedle head. having. an angularly. shaped'weye, communicating with a slot formed between a tongue at one side of the needle head; .formed: integrally therewith, to guidethethread when inserted through the slot into the eye, said eye being also shaped-to lock the thread after same has been inserted within the eye the said tongue-normally being positionedagainst the body of the needle headeand beinsgshaped to prevent the cloth: or fi bersfrom catching, or tearing when the. needle is. passing throughthe fabric or other,-material in :the act of sewing;

Themain .object of my invention is to provide a needlesthat will grip the thread lin such manner that it maybe securely gripped within approximately one-half"inch 'of the" end thereof, by having the upper end'iorzthe eye shaped to pinch ..the.. sides.. of the ethreade without cutting same the said ey e. being {shaped :to griplvarious sizes .of-. threads... yarns, ..or. othen. cords.

Another; object .of. the. invention: is to provide a .needle that is.very advantageous: and (practical in the use of surgery, same having the special advantages of permitting different stitches to be made due to the open end of the eye, said eye having one end narrower than the other end, i. e. the roof of the eye of the needle in one type is of a Wide range and the opposite end of the eye having a narrower gauge; also to provide a needle in which the narrow and wider ends of the eye are reversed in a machine type needle. For use in surgery the eye would have one side making easy and quick outlets of the eye for removing a loop of thread without disturbing the ends; also in event the needle is to be re-threaded into a loop the slot will allow a quick and easy method of assembling the loop within the eye, at the same time giving the eye a locking action on the thread.

Another object of my invention is to provide a needle having a threading slot that can be threaded in a few seconds by a blind person with ease and with very little guidance; the said needle being provided with an upper endhaving a blunt portion extending slightly above the 3 Claims.

upper end of a tongue on the opposite side of the threading slot; the blunt portion being of curved shape disposed oppositely to a curved portion at the outer end of the tongue.

Another object of my invention is to provide a needle that preserves strength to the needle eye where it is most needed, without enlarging the head of the needle.

Other objects of the invention are to provide novelfeaturesaof construction, for, whichj..protec,-, tion. is .desiredJ] lnsaiddrawingsz- I Figure la is. a..side.elevation of...one embodi mentofmyneedle.

Fig. 11 is a section through a still further modified form of needle.

As shown in Figs. 1-8 inclusive, my novel needle comprises an elongated body I of metallic or plastic material of oval cross-section, having a pointed lower end Ie. An eye la is provided adjacent the opposite end thereof, said eye having a semi-circular lower end and having upwardly converging side walls Id which substantially meet at the upper end of the eye. As shown, the side walls Id and lower end of the eye Ia are beveled as at 16 at opposite sides of the eye la to reduce the thickness of the opposed side walls, so as to grip by wedging action the thread 2 inserted into the eye la when the thread is moved upwardly within the eye, the edges lb being preferably polished to prevent injury to the thread 2.

A slot la is provided in the said opposite end of the needle, extending longitudinally of the needle, with its lower end opening into the lower wider portion of eye Ia at one side thereof, and its upper end opening through the upper end of the needle, thereby providing a tongue lm which may be flexed laterally outwardly at its lower end Ir when a thread is passing through slot lc into eye la, as shown in Fig. 8, the tongue lm normally lying beside the adjacent portion of the needle body, as shown in Fig. 7.

As shown in Fig. 7, the upper end of the needle body is relatively blunt but is curved slightly downwardly as at I y from its outer edge towards the upper end of slot 10, while the upper end of tongue lm slopes oppositely as at m to form with the portion lg a shallow'V-shaped groove' at the upper end of slot lc to facilitate entry of thread 2 into the slot 10, particularly when the needle is to be threaded by a blind person, ,or

ing one end pointed; an eye adjacent the opposite end of the body relatively wide at its lower end and having upwardly converging side walls adapted to grip a thread inserted into the eye and shifted upwardly; said eye being centered axially of the needle body, said body having a slot in said opposite end extending longitudinally thereof with its lower end communicating with the lower end portion of -.the eye, and the upper end of said slot extending'through said opposite end of the body, thereby forming a tongue normally contacting the adjacent portion of the one having poor eyesight, or when being threaded under bad lighting conditions.

Instead of havin an oval cross-section, the needle body I may be of substantially diamondshaped cross-section, as shown atla: in Fig. 9; or may be of circular cross-section, as shown at ly in Fig. 10, the eye la and slot Ic however being similar to those previously described; also instead of the side of the eye la having beveled walls as shown in Figs. 1-10 inclusive, the walls of the eye la may be rounded, as shown at 12 in Fig.11.

My'needle is so designed that the side walls of the eye la will grip the thread 2 in such man ner'that the thread may be'secured tothe needle approximately within one-half inch from its end, the walls pinching opposite sides of the thread. without cutting same, "and the eye" la being shaped to grip various sizes of threads, yarns, and cords.

I do not limit my invention to the exact'forms shown in the drawing, for obviously changes may be made therein within the scope of. the claims.

' Iclaim:

1. A needle comprising an elongated bodyhav "needle body throughout its length and adapted to be. flexed laterally when a thread is being passed through'the slot'into the eye.

2. Ina needle as set forth in claim 1, the walls of theeye at opposite sides thereof being beveled to reduce the effective width thereof.

3. In a needle as set forth in claim 1, the walls of the eye at opposite sides thereof being rounded to reduce the effective width thereof. I
